What if it could also do vertical tracking? Who would use it then?Which sports?

His is not very accurate when <200m away.What if I could make it work up close? Would this be valuable?Which sports?

If you can help me I appreciate it. Thanks for your time.

Any flying sport/activity desperately needs (full) vertical tracking. I see huge potential in this. Also, have you noticed in soloshot videos there is shot of base on a boat? If I want to allow to move base during filming and system is GPS based you need GPS receiver in the base too.
